With the increasingly severe international situation, explosive detection has become an important topic of national security, and the rapid and efficient chemical sensors have attracted people's attention. In this work, a novel sensor CSA was synthesized through cholesterol succinate and 1-Aminopyrene. UV-vis and fluorescence spectra showed that CSA had a typical aggregation-induced emission(AIE) effect in THF/H2O solution, and explosive CL-20 could effectively quench this fluorescence. In addition, the seal and cotton swab prepared by CSA can specifically detect CL-20, providing a platform for the practical application of CSA in public safety.

随着国际形势的日益严峻，爆炸物检测已成为国家安全的重要课题，快速，高效的化学传感器引起了人们的关注。在这项工作中，通过琥珀酸胆固醇和1-氨基py合成了一种新型的传感器CSA。紫外可见光谱和荧光光谱表明，CSA在THF / H2O溶液中具有典型的聚集诱导发射（AIE）效应，而爆炸性CL-20可以有效地猝灭这种荧光。此外，CSA制备的海豹和棉签可以特异性检测CL-20，为CSA在公共安全中的实际应用提供了平台。
